PAPER-FILE.

SPECIFICATION forming part Of iettl Patent No. 436,214, dated September 9, 1890.

Application filed May 9, 1890. Serial No. 351,150. (No model.) y

- ters, circulars, bills, tablets, or other articles in a box, having a lfollower adapted to be clamped so as to press and hold the papers in position, all of which will be fully set forth in the description of the accompanying drawings, makinga part of this specification, in which- Figure l is a side elevation of my improvement. Fig. 2 is a section on line x, Fig. l. Fig. 8 is a top plan view of the clamp shown in Fig. l. Fig. 4: is an end elevation of a modified form. Fig. 5 is a -central longitudinal section of Fig. et.

A represents the base of the le-box, and B the stationary end.

C represents two side rods, upon which the follower slides.

D represents a sleeve provided with tubular collars a at either end, which form journals for the sleeve D to move upon. These tubular collars are cut away inside of the sleeve on the inner side, as shown at E, Fig. 2, so as to allow the sleeve D to be clamped to the rods by mechanism on the interior of said sleeve. Ihave shown two forms of interior clamping mechanism.

In Fig. 2, I I represent locking-bars, the inner ends of which are inclined so as to be acted upon by the wedge F. This wedge is provided with a thumb b, as shown in Fig. 1,

so as to operate rapidly.

d represents a stationary arm rigidly secured to the sleeve D, and provided with ears e to which the handle of the wedge F is pivoted.

g represents a spring for holding the wedge F normally down so as to force the lockingrods I I outward against the bars O.

L represents a semicircular bracket, the ends of which are rigidly secured to the follower K. It passes around the sleeve D and rigidly attaches the same to said follower.

In the modification in Figs. 4 and 5, instead of locking-bars I, I provide a vibratory sleeve O. On the ends of said sleeve O are formed cams N.

P represents a knob secured to sleeve O, projecting up through the slot in the sleeve D above the handle d. The operator grasps the handle d and turns the knob P to rotate the cam-sleeve O, so as to force it againstthe carrying-rods or release it therefrom.

The mode of operation is as follows: The operator takes hold of the handle d and releases the clamp, and the follower K is allowed to slide freely back and forth upon the ways C." The clamp is operated to lock it in any desired position. This form of follower and clamp possesses many advantages over those hitherto used. The follower K is rigidly secured upon the bars O, so that any desired amount of compression may be put upon the article held between the follower K and the stationary end B. It is subjected to little or no lost motion and is not liable to get out of order.

The tubular sleeve D is a very important feature of my invention, as it forms a lateral brace to incline Aways C and furnishes means for carrying the locking device within the same so as to lock the sleeve D to the ways C by a' device carried inside of said sleeve. 8o The ways O are thus stiffened against outward or inward strains, and they are clamped in any desired posit-ion without strain upon the ways, which are preferably made of wire,

so as to be light, and are therefore liable to be bent or injured unless so braced and supported.

Having described my invention, what I claim, ism

'1. In a paper-le, the combination, with a 9o base A, an end B, a horizontal rod C, and a follower K, of a slotted sleeve D, secured to the follower and having a bearing sliding on the rod to move the sleeve lengthwise thereupon, and a clamp mechanism for rigidly lock- 95 ing thel sleeve and its bearing at any point along the length of the rod, substantially as described.

2. In a paper-file, the combination of the follower K, rigidly secured to the sleeve D, roo provided with tubular bearings a, in combination with the locking-bars I and the Wedge F, substantially as herein specified.

3. In a paper-iile, the follower K, supported upon the sleeve D, rigidly secured thereto, ing device carried Within said sleeve project- 1o and provided with tubular bearings a and ing up through the same above said handle d,

handle d, secured centrally to said sleeve, and substantially as described.
